Abstract: Interest is an interest in an object that comes from the heart.
Talent is a condition in a person that enables him with special training to achieve a special skill, knowledge, skill.
For this reason, an expert system for determining students' interests and talents was designed.
The method used in this research is the certainty factor (CF) method.
The results based on the characteristics experienced by these students show that the type of interest and talent that exists in these students is linguistics with an expertise level of 0.
66 and a percentage of 66% and has a fairly good accuracy score.
Keywords: certainty factor.

This expert system becomes an expert in answering questions in solving a problem .
The method used is the certainty factor method.
by proving the uncertainty of an expert's thinking in detecting existing problems.
Previous research also used this method, resulting in a fairly appropriate confidence percentage in detecting this problem From this research, the results of testing of this method showed that 2 disease data were detected with 10 symptoms experienced.

The results of the diagnosis CONCLUSION From the test results obtained based on the characteristics experienced by the student, the student's type of interest and talent is linguistics with a skill level of 0.
866 and 66% and has a fairly good sharpness value.
So from the results above, this method can be used to help make it easier for teachers to group students according to their interests and talents.
